Patrick Campanale explores UV printing slate coasters with the xTool O1 Omni, aiming to create a high-margin product. He emphasizes that this process is relatively straightforward and provides a practical starting point for creating custom coasters despite being early in his long-term testing phase.
The video details the workflow, including scanning and aligning coaster designs within xTool Studio, selecting appropriate white and color layers, and adjusting print settings for a flat UV print. Patrick also addresses design choices and their impact on print quality, noting that graphics with lighter colors tend to perform better on dark slate.
Important considerations discussed include ink costs, estimated print times, and the selection of RGB versus CMYK color modes along with the Rock/Stone preset. Patrick acknowledges potential mistakes in graphic selection and highlights the importance of choosing designs suitable for UV printing on slate to ensure readability and vibrancy.
The video concludes with a scratch test demonstrating durability and outlining pricing strategies based on material costs and ink usage, suggesting ideas for sellable coaster variations while encouraging viewers to support his channel through memberships or affiliate links.
